Beit kn wn that I, Mrn'o RO'L' N' S, aat l zen of the .UnitedStates, residing; in Boston,

in the county of Suflolk andStatefoflUassa- .chusettjs, have invented-an Improvement in- Railway-Cars, of which thefollowi'ng 'descripe; -tio n in connection with the accompanying drawings, is a specificationdikr characters on the drawings representing like parts.

The present invention has for its object to 1; provide a car of the class described in which the step leading from the vestibule is 'co'nff I nected with the door thereof, so thatwhen the door is moved into its opened position. the step is automatically lowered-,zand wheli the .door is movedinto its-closed positionthe step is automatically raised or folded up. into aninoperative position. Provision is made for operating the step at the initial 1nove-' nient-of the door from its closed into its open positionandatthe latter part of. themove- -m' ent of the-door from its opened into its;

closed position.- Theidoor ma v 'be1o'perated by powerunder control of the operator with- 'inthe vestibule. -'.Provisioniisalso made'for closing the epening above the a e-p when the door is close These and, other. features of thisinvention will be pointed out in the claims'at the end of this specification.

Referring J'uore particularly to Figs. 3, 4.

. and 5,-the' step 9 has'connected to it one end of a link 10, having its other end joined to one arnrl-Z of a lever-13, pivoted at 14 in a. bracket 15, secured to the car-body. The lever 13 1s provided with a slot 16, into which. extends a stud orfpin 17 on the end of an upright link or rod 18, having an enlarged head 19,'which. is providedwith a slot 20, into which extends a pin or stud 21 on an arm 22 of a lever 23, pivoted at 24; and operatively connected with the car door d. In the present instancethe lever 23 is operatively'connected witir the door d, so that the said lever is operated by the door hile the latter is moving a portion of its travel and is not op-' erated by-said door during another portion of its travel in the same direction, r

In practice it is ,referredto have the step g lowered" whilejt e door is being opened 'about'twellve inches ofits travel and togbe raised while the door is being closed and. dur' ingthe last twelve inches of its tra'vel. In

the present instahceone construction of mechanism is shownfor accomplishing this result. To'this end the door d has attached .to it a device for en a stud or roller 25 .onthe upper end 0 t e e ver 23, which device isherein shown as a plate or casting 26, provilled with-a passageway or slot 27,

into f whi'ch the stud or. roler 25 may move; 'andwitha curved finger 28f When the door is-closed, the stud 25 1s in the pz ilesageilway or ent e door gagesit this move-- g, assess ward and turns the lever 13 from its position indicated by full lines, Fig. 5, into that indicated by dotted lines, thereby through the link turning the step 9 down into its hori- 5 zontal or operative position. The step g assumes its horizontal positionat or about the time the door has been 0 ened about one foot, and at such time the ever 23 has been turned so that the stud 25 is disengaged from the slot 27 and on the further movement of the door passes under a guard or stop, herein shown as an angle iron or bar 35, which can tends across the door and 'is secured thereto. The guard or stop constitutes one form of means for preventing the step g being accidentally r1 maliciously folded or turned up While the door is open, thereby avoiding accidents from this'source'.

On the return or closing movement of the door the step 9 remains lowered until the door has been closed except about one foot or it may be any other desired distance deemed insufli'cient for the passage of a person. into or from the car, and at or about this time the curved finger 28 engages the roller 25 and on the further movement of the door causes the lever 23 to be turned from its dotted-line position, Fig. 4, intoits full-line position, thereby throu h the link 18, lever 13, and link 10 turning the step 9 u into its inoperative or full-line position. (S own in Fig. 5.) Provision is also made for covering the space which.

is above the upper step f when the door is closed, said space being 0 en or uncovered when the door is'open accomplished, as herein shown, (see Fi s. 6 and 7,) by means of a cover or section, W rich may be made as herein shown, and consists of an inclined piece 37 and a horizontal piece 38, secured to the inner side of the door at or near the bottom. of the same. The inclined piece 38extends from the door down to near the upper surface of the platform or floor; of the vestibuleand serves to prevent passengers standing on the cover or section, which might interfere with the operation of the door. Provision is made for guiding the free end of the'cover or section 37, and for this purpose a hook-shaped piece 40 is se- 5o cured to the underside of the horizontal piece 38 and embraces a depending flange or rib 41 on a plate 42-, secure to the vestibule platform or floor as clearly shown in Fig. 6. The door-d may be provided with rollers 44, which run on a track 45. The car-body on its inner side is formed'so as to permit the cover 37 't'o-pass Within the car when the door is opened.

The door d may be operated by hand, but it ma T be preferred to operate the same by power, which may be accomplished, as herein shown, by attaching to the door one end of the rod. of a piston 51 located in a cylin der 52, which is attached to the car-body and 6 5 is supplied with air under pressure which is T result may be.

admitted into the opposite ends of the cylinder by pipes 53 54, w ich lead. to a valve-oasing 55, containing a suitable valve having a handle 56, by, turning which either end of the cylinder may be connected with a suitable source of pressure carried by the car and not herein shown.

In Fig. 2 the car is represented as provided with four doors, two on each side, and three of these are closed whilethe fourth is open, and by reference to Fig. 2 it will beseen that onlyone step 9 is its lowered position.

'lhe hooked plate 40, attached to the bottom of the cover 37 and movable with. the door extends substantially the width olithe door and cooperates with the flange 41 onthe plate 42, so as to lock the door against lateral movement. In practice the track s5, on which the door runs, extends but a short distance into the doorway, and the hooked late serves to holdthe doorway when in its 0 osed position against dis lacement by internalpressure in a lateral irection.

. The invention is herein shown as embodied in a railway-car having a vestibule but it is not desired to limit the invention in this respect.
